This video explains about Lac Operon Regulation - Catabolite Repression: Role of cAMP, CAP & Glucose.
Lac Operon: [ Ссылка ]
Operons are groups of genes clustered in the bacterial DNA regulating the expression of functionally related proteins.
In E. coli half of the genes are clustered into operons which are involved in particular metabolic pathways.
Lac operon model was proposed by Jacob & Monad.
Lac Operon is responsible for the transport and metabolism of lactose.
cAMP mediated regulation of lac operon. adenylate cyclase converts ATP to cAMP which is inturn inhibited by high level of glucose.
